Abstract
A discharging ball valve mainly solves the problem that accumulated materials at dead angles in an existing discharging ball valve influence operation of a gear pump. The discharging ball valve comprises a welded base (1), wherein the welded base (1) is welded at the bottom of a degassing tank, a valve body (6) is connected with the welded base (1) through a thread and sealed by an O-shaped sealing ring (2), a ball body (3) and a sealing ring (4) are disposed in the valve body (6) and fixed through baffle rings (5), filler (7) is arranged between a valve rod (8) and the valve body (6) to seal, the filler (7) is fastened through a filler cover (9), and a handle (10) is arranged on the valve rod (8). The dead angles between the degassing tank and the ball valve are eliminated so that grease in the degassing tank is thoroughly discharged and work conditions of the gear pump are improved.
Description
Technical field
The utility model relates to chemical production equipment, and is a kind of for the supporting a kind of emptying ball valve of the chemical industry equipment of lubricating grease degassing technique.
Background technique
[0002] in existing chemical production technical, in the LUBRICATING GREASES process, degassed by degassing tank, when temperature is down to 110 ℃ of left and right sides, through its bottom drain hole, discharging valve, the gear pump blowing, generally use at present Flange Ball Valves as discharging valve, the common flange ball valve is connected by flange, flange and short tube welding, the other end and degassing tank welding, this mode forms the dead angle owing to increased section of a pipe between degassing tank and ball valve, in process of production, stop blowing after, grease temperature can be down to normal temperature, solidify, the lubricating grease meeting solidification-stack of degassing tank inside is in degassing tank and ball valve joint, because this part lubricating grease resistance that solidifies is large, viscosity is high, when again producing the starter receiver pump, load increase for pump is very large, and pressure is very high, often causes the damage of pump and affects production.
Summary of the invention
Exist the dead angle buildup to affect the problem of gear pump operation in order to solve existing emptying ball valve, the utility model proposes a kind of emptying ball valve, by changing the Placement of ball valve, eliminate the dead angle between degassing tank and the ball valve, thereby address the above problem.
The technical solution of the utility model is: this emptying ball valve comprises the welding base, the welding base is welded on the degassing tank bottom, valve body is threaded connection the welding base, valve body by " O " RunddichtringO sealing, spheroid and seal ring are housed in the valve body, and spheroid and seal ring are fixed by baffle ring, are provided with packing seal between valve rod and the valve body, filler is fastening by follower, and valve rod is provided with handle.
The utlity model has following beneficial effect: welding base of the present utility model top is the concave spherical surface shape, is consistent with the degassing tank end socket, reduces the distance between spheroid and the degassing tank, eliminates the dead angle between degassing tank and the ball valve.The utlity model has following beneficial effect: by eliminating the dead angle between degassing tank and the ball valve, eliminate the buildup in the dead angle, make the complete discharge of lubricating grease in the degassing tank, improve the operating conditions of gear pump.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure: 1-welds base; 2-" O " RunddichtringO; The 3-spheroid; The 4-seal ring; The 5-baffle ring; The 6-valve body; The 7-filler; The 8-valve rod; The 9-follower, the 10-handle.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this emptying ball valve comprises welding base 1, valve body 6, welding base 1 is welded on the degassing tank bottom, and valve body 6 is threaded connection welding base 1, between valve body 6 and the welding base 1 by " O " RunddichtringO 2 sealing, spheroid 3 and seal ring 4 are installed in the valve body 6, and spheroid 3 and seal ring 4 are fixing by baffle ring 5, are provided with filler 7 sealings between valve rod 8 and the valve body 6, filler 7 is fastening by follower 9, and valve rod 8 is provided with handle 10.Welding base 1 top is the concave spherical surface shape, is consistent with the degassing tank end socket, reduces the distance between spheroid 3 and the degassing tank, eliminates the dead angle between degassing tank and the ball valve.The utlity model has following beneficial effect: by eliminating the dead angle between degassing tank and the ball valve, eliminate the buildup in the dead angle, make the complete discharge of lubricating grease in the degassing tank, improve the operating conditions of gear pump.
